I purchased this charger to replace my old charger that I had for 30 years. What a difference and upgrade to my tools for charging. Here are my observations.Pro:1. [ Quick Charging] I love the 4-level adjustable current 2A/10A/25A/Auto setting. I can set the charger up to what I need whether I am charging a car battery, motorcycle battery, or tractor battery.2. [ Fully-automatic Charging] The Auto setting is my favorite because I can setup and let it go. I would setup at the end of a night and let it go all night. It automatically shuts off and the battery is full charged.3. [8-Stage Charging Program] The intelligent 8-stage charging works flawlessly in the auto setting. The best is the information it displays during the process. Works as stated.4. [Engine Start & Winter Mode] I have used this mode twice. It provides 100Amps of charge. It helped my get my car started for work on a very cold morning.5. [Overall performance] No complaints works as stated and meet my needs to dealing with all the batteries in the household.6. [Price] Product is low price with high quality. Meets my expectations without breaking the bank.7. [Durability] Case is well built and well mold to stand the dirt and grime of a typical garage.Cons:1. [Case] A firm case would be nice for storage. Just using the box for storage. Could be an added item to improve the product.2. [Screen] Screen is average quality for the product.Overall, I would rate this product as a 5 star. It meets my expectation of quaility, ease of use, value for the money and versatility. Excellent addition for normal household use.

Great charger and compact

I bought this to replace another brand that failed right after the warranty ended. About 2 months after. While the two works the same way, I've had this one for a long time. I received this around Sept 2021. This charger has been used on some really dead batteries. Some I had to put jumper cables on just to get enough voltage for the charger to see it is connected. On a few occasions, it ran at the maximum current for several hours with the fan whirring away at full speed. It just kept charging until the battery was completely charged.When my other brand failed, I looked inside. It was cheap made. I haven't looked inside this one but to charge sometimes dual automotive batteries which requires running at the maximum current for several hours, plus still last well past the warranty, it has to be well made with some good components and a good design.I've only used the engine start feature a couple times. It did work. If it all possible tho, I'd recommend a proper charge. If in a hurry, it will start a modern car. May require two times for a good sized truck. Make sure you wait a bit between the two engine start runs. It can overheat the charger if ran to close together. Check the manual but mine wants a 90 second wait.If I needed another charger, I'd certainly buy another like this one. I'm very happy with the way this charges and the durability. It performs a safe charge and detects bad batteries very well.

Very nice battery charger, Its connected to my trailer battery 24/7, at first I thought it was great, later I notice it doesn't auto restart nor does it maintain or keep the battery charger up, I'm always having to manually start it. Light get very dim. Or my heater stops working, check battery it's at 10V. Charger should of trun on but it doesn't.

This is the best purchase I've made in years. Thank you to the manufacturer. Great low price. So simple my wife can hook it up, and she admittedly knows nothing about charging a battery. Here's why a snagged this. My wife left the door ajar in her SUV and ran the battery down to nothing. I jumped it with my car but figured her battery needed some TLC. Hers is a 2023, mine is a 2017. So mine was closer to death than hers. The charger came overnight. I connected the red cable and the black cable to her battery... directly to the battery and plugged it in. I didn't disconnect anything, it was still in the vehicle. The charger display lit up. Wow! I didn't even hit Start yet. And it started diagnosing the battery on its own. Magic! I was shocked. It went through all 8 stages and desulfationed and then deep charged it. It took about 5 hours. It sat on 99% for quiet awhile, then 100% and shut itself off. Voila! I took the cables off and moved it to my 2017 battery. Same thing happened, it just went to work. I left it overnight and in the morning, 100%. I'm telling you, whoever designed this was at genius level. There were no side effects with electronics, loss of radio stations, or anything. I'm impressed. I would buy this again in a heartbeat. It makes you want to tell all of your friends and put it on their batteries just so they can experience the magic too. And it's pretty compact compared to the old battery chargers. Get one! Highly recommended!

Works very well, was able to revive a neglected battery over about a week of sustained efforts!
